Hi All, |
2 |
|
3 |
I do not seem to be able to run star with the correct options despite some |
4 |
experimenting ... and was hoping you could correct my errors. |
5 |
|
6 |
I seem to have done this successfully in the past, but I am getting |
7 |
inappropriate results this time round. This is the fs I am trying to back |
8 |
up: |

The fs is shown to be 1.1G large: |
39 |
======================================================== |
40 |
# df -h |

44 |
======================================================== |
45 |
|
46 |
I want to save the backup on a USB drive on /media/sda1. Therefore I ran star |
47 |
as root like this: |
48 |
|
49 |
# cd /dev/sda1 |
50 |
# star -xattr -H=exustar -c -f hda5_root1.star /media/hda5 -C /media/sda1 |
51 |
|
52 |
After a lot of messages like these: |
53 |
======================================================== |
54 |
star: No such file or directory. Cannot listxattr |
55 |
for '/media/hda5/usr/sbin/dumpfilter'. |
56 |
star: No such file or directory. Cannot listxattr |
57 |
for '/media/hda5/usr/sbin/ethtool'. |
58 |
star: No such file or directory. Cannot listxattr |
59 |
for '/media/hda5/usr/sbin/traceroute6'. |
60 |
star: No such file or directory. Cannot listxattr for '/media/hda5/usr/tmp'. |
61 |
star: No such file or directory. Cannot listxattr |
62 |
for '/media/hda5/usr/share/firstboot/modules/rootpassword.py'. |
63 |
======================================================== |
64 |
|
65 |
... it eventually completes. What puzzles me is the size of the star archive, |
66 |
which compared to a vanilla tar archive is massive: |
67 |
======================================================== |
68 |
# ls -la /media/sda1 |

77 |
======================================================== |
78 |
|
79 |
Is this difference in size between the hda5_root1.tar and hda5_root1.star |
80 |
expected? I also show above the previous back up I did as a comparison |
81 |
(although I cannot recall exactly what options I chose to run star with). |
